A spate of fatal accidents spotlights a struggling rail service, per USA Today's Trevor Hughes.

The big picture: Amtrak has seen three high-profile accidents, which killed a total of 6 people and injured nearly 200, since December. "While all three of Amtrak's most recent crashes [in as many months] appear to have different causes, some critics are calling for changes to the organization's approach to safety."
